Things to note when spraying fruit trees in summer: fruit growers should keep these points in mind
We are now in the dog days of summer, with extremely high temperatures. For orchard management, the high-temperature climate is conducive to the harm caused by weeds, pests and diseases, so prevention and control management must be done well. Pest and disease control cannot be done without spraying pesticides, but spraying fruit trees under high-temperature conditions has certain restrictions. If handled improperly, it will backfire. So what should be noted when spraying fruit trees in summer? Let's find out together.
1. The pesticide concentration should not be too strong
When spraying fruit trees in high-temperature weather, note that the concentration of the pesticide solution should not be too high, because in a high-temperature environment the water in the solution evaporates very easily, so the water in the pesticide will spread and disperse very quickly, which also increases the concentration of the solution to a certain extent. If the concentration of the solution itself is already relatively high, it is very easy to cause pesticide damage to fruit trees under high-temperature conditions, so farmer friends should strictly follow the application standards when spraying in the high temperatures of summer.
2. Do not spray at noon
Noon in summer is the hottest time of the day. Many farmers are eager for quick results and like to spray at the high temperatures of noon, believing that the pesticide effect will take effect faster this way. In fact, this is a wrong practice, because the temperature at noon is extremely high, and pests will also be correspondingly reduced. Spraying at noon not only fails to reach the pests themselves, but also, combined with the rapid volatilization of the pesticide effect, the effectiveness will be greatly reduced. Therefore, it is recommended that fruit tree growers avoid the high-temperature period at noon as much as possible and choose to spray in the evening.
3. Protective measures should be taken well
Under high temperatures, people sweat a lot even without exercising, let alone doing physical work like spraying. To stay cool, many fruit growers wear short sleeves and shorts when spraying, which is a very dangerous behavior. High temperatures cause the pores of human skin to expand. After the pesticide solution volatilizes and drifts, it will come into contact with human skin, and in this way it will be absorbed through the pores, thereby causing human poisoning. Therefore, no matter when spraying, protective measures should be taken well to avoid pesticide poisoning.
4. Do not spray in the early morning
The early morning weather is cool, so it should be the best time to spray, right? But why can't you spray then? This is because the temperature in the early morning is relatively low. If you spray too early, the dew has not yet completely evaporated, and the pesticide will be diluted by the dew on the plants, which reduces the concentration of the solution and causes poor pesticide effectiveness.
